Yeah - this isn’t a “vaccine” as we know it.
It’s a drug that makes your body produce proteins that LOOK like the virus to your immune system and then your immune system will supposedly get trained on it.
But it takes more than a few days for your body to produce enough of the proteins and for your immune system to figure out how to easily attack it.
So this isn’t surprising.
Yeah, I agree...
“Yeah - this isn’t a “vaccine” as we know it.”
True, but even the regular vaccines take time to build immunity AND are not 100% effective.
